Glechoma hederacea, Dronten, Roggebotbos © Hans Jonkman


Glechoma hederacea, Duin- en Kruidberg


The mine begins as a narrow corridor, with the fraa in fine grains along the sides. In the next section the corridor is much wider and more closely wound, forming a secondary blotch; the frass now forms pearl chains. In the final section the corridor is again narrower, rather straight and especially interparenchymatous, greenish when lighted from behind. Pupation outside the mine, but the puparium often sticks to the leaf.
